how to create queries like this...

[eluser]tusukgigi[/eluser]
this is my view


if(count($getCountry)){
foreach($getCountry as $key=>$list){
echo $list['district_name']."<br />";
echo $list['city_name']."<br />";
}
}

$getCountry is a variable from controller

this is my model database
SELECT DISTINCT city_name, district_name FROM district LEFT JOIN city ON city.district_id = district.id

and this is the result

country1
jakarta
country1
bandung

country2
newyork

....

there is a COUNTRY repeat's
